Why not EJB/JPA?

• While EJB/JPA is supported by ADF •  ADF BC is the strategic ORM for Fusion Apps •  And the focus of this course

The architecture of an ADF application is defined by its reusable components

and supporting structures.

ADF out of the box different types of reusable components. What are they?

ADF Reusable Artefacts •  What are the primary reusable ADF Business Component artefacts?:

–  Entity Objects (EOs) –  View Objects (VOs) –  Application Modules (AMs) –  Framework Extensions Classes

•  What are the primary reusable ADF Controller artefacts?: –  Bounded Task Flows (BTFs) –  Task Flow Templates

•  What are the primary reusable ADF Faces artefacts?: –  Page Templates –  Skins –  Declarative Components –  Utility Classes

Hmmm, did anyone consider SDOs? I wonder if these are important now?

What are the primary structures the reusable ADF components are defined

in and what construct are they delivered in?

ADF Structures & Deployments •  All ADF components must exist in a JDeveloper Project •  One or more ADF Projects must live in a JDeveloper Workspace

•  Workspaces, Project and ADF Libraries are a key player in an ADF application’s architecture

•  Components may be shared amongst JDeveloper Projects –  Within a Workspace by defining inter

project dependencies –  Or externally via ADF Library JARs

consumer by another Workspace Project

Complete Set of ADF Architecture Artefacts •  ADF Business Components

–  Entity Objects (EOs) –  View Objects (VOs) –  Application Modules (AMs) –  Service Data Objects (SDOs) –  Framework Extensions Classes

•  ADF Controller –  Bounded Task Flows (BTFs) –  Task Flow Templates

•  ADF Faces –  Page Templates –  Skins –  Declarative Components –  Utility Classes

•  JDeveloper –  Workspaces –  Project –  ADF Libraries

•  These are the artefacts supported by the framework itself •  This doesn’t exclude your own Java code

Conclusion

•  The architecture of an ADF application is always defined by its reusable artifacts and how they're brought together

•  Identifying, documenting and designing your reusable components should be a primary task for team leads and ADF artifacts
